375 feet on the dip of tne deposit (630), all in ore. The ore in sight
amounts to many thousand tons. During 1885 the company mined
about 9,000 tons. New crushing and concentrating machinery for work-
ing the ores on a large scale for copper, together with an air compressor
for running power drills and underground pumping machinery, have
been added in the past year. The following is the analysis

The Sulphur Mines Company, of Virginia, has a large body of pyrites
situated about 1 mile northeast of the Arminius mines, on the same
deposit. There is a branch railway from Tolersville to the mines. The
workings are quite extensive, and several shafts have been sunk upon
the vein and through the gossan to the pyrites. The analysis of the
ore is practically the same as that of the Arminius. The output from
these mines in 1885 was about 4,000 tons.
The property owned by Mr. Charles Lennig has not been worked
since the last report.
North Carolina.—There is a deposit of pyrites near Gastonia, in Gas-
ton county. This deposit is small on the surface, being about 2 feet in
width, and can be traced for half a mile or more. A shaft was sunk on
the vein to a depth of about 45 feet, when the ore gave out. The analy-
sis gave the following results

This ore was supposed to carry from $6 to $10 per ton in gold, which
proved not to be the case.
jSTear Charlotte, Mecklenburgh county, is a pyrites mine, which is
being worked for gold and apparentlj^, with success. The average is
nearly $7 per ton in gold. The sulphur is not utilized, as it is too much
mixed with rock. The vein varies from 1 to 7 feet in width, the deepest
workings being over 300 feet. The ore is crushed and pulverized, and
the gold is saved On Rittinger tables.
